Tonll wlinmfit-my cantera:

Be 'it known thatI, "JAMES B. Magnum, a citizen of the UnitedjStates,,residin at Brooklyn, in the county of ',Kings and i tate of New York,have invented certain new and useful Im rovements in Flying-Machines;and I do veclare the following to be a full, clear, andexact descriptionof the invention,

` such as will enable others skilled in the artto which it a'ppertainsvto make and use the same. v

This invention relates to flying machines and has for its object toproduce a flying machine supported, propelled and guided by rotating a1rprope lers.

Another .object is to produce a device of this kind which vwill be.convenient and eliif cient in operation. To accomplish this is provideda lplurality of horizontally and vertically disposed cylinders havingpropeller blades at the mouth thereof whereby a partial vacuum isAformed in front of said propeller blades and the air is congested in theair cylinders'behind said blades.

Another object is to -provide such an arrangement of said horizontallyland vertically disposed cylinders that air blasts generated by saidcylinders contact each other in such a manner as to momentarily divertthem from their directcourse of escape from their respective cylinderstemporarily re'- ta-rding their progress thereby still further au oenting the compression and resistance .4 an kthus accelerating the.movement of the v and scope of the invention.

not vlimited to these las the.l details of constructionan'd` combinationmay be greatly varied without departing from the spirit In the annexeddrawing forming a art of this specification' in which like rel erencecharacters refer to like parts thrpu hout the' several views and whichare for i ustrative purposes and therefore not drawn to any i.particular scale, Figure lis a-front elevationj. Fig. 2 isa top planvient;- Fig. 3 is a ln @1 i'tudinal sectional View. The mam features'ofthelyelitically disppsed ope-mended .Cylnes 1 andthezhprzontallydisposed cylindersQ.

Qns of each of these is provided. ,011. .each VSide of thej longitudinal.central plane of4 the in achine and'they meet each other at right an-`gles as shown. Said cylinders are supported upon a' frame 3 havingcross braces 4 and are supported by forward wheels 5 and a rear wheel 6,said wheels having spring connection as at 7 with the frame whereby themachine will not be jarred excessively or broken when it descends. saidframe is provided a gasolene engine 8 or other source of power. Theshaft 9 of said, engine is provided with a forward sprocket wheel 10 anda rear sprocket wheel 11. Clutches 12 and 13 serve to disconnect saidsprockets from said shaft. The sprocket 10 is provided with a chainpassing over the `upper sprocket 31 rotatably mounted upon the forwardcenter shaft 14, suitably supported as at 16 and connected tolaterally.ektending shafts 17 which are in turn geared to horizontallylying shafts 18 coaxial with the cylinders 2 and carrying at the forwardend a propeller 19.

A 'sprocket chain connects the sprocket wheel 11 with the sprocket 20upon the shaft 21 and the forward end of said shaft is con* nected bylmeans of the clutch 22 with the beveled-gears 23 intermeshing with thegears on the rear laterally extending shafts 24 having gears intermeshinwith gears on the vertically extending sha ts 25 carrying the propellers2G in the upper part of the cylinders 1.v

The rear end of the shaft 21 is provided with a beveled gear 27intermeshing with the horizontal gear 28 in turn. inter-meshing with thebeveled gear 29 upon the short shaft 30 carrying thc rear propeller 31.lThe short shaft 30 is carried kin a bearing support 32 rigidlysecuredupon the rotatable vertical support 33 carrying the wheel 6. A wheel 34upon said vertical sup )ort Sis adapted tol receive a belt or the llke35 cbrln'ected to a.

clutch 38 is pr'ovi ed intermediate the ends of the shaft 21. A link andlever 39 and 4:0

lplaced in a convenient positionenables the operator to operate saidclutch.

. The operation of the machine is a fols About midway of' lows :'-Thegasolene engine is started as usual and any of the propellers 19, 26 or3'1 may be thrown in gear by means of the clutches 12, 13, Q2 and 38,thus causing the machine to move upwardly or downwardly or forwardly asdesired. The steerings explained.

I claim as new and desire to-secure by U. S. Letters-Patent is In amachine of the character described, a pair of horizontally projectingcylinders, a

thereof arranged adjacent the outlets of the 15 horizontally projectingcylinders, fans jonrnaled in all of said cylinders, a mechanism I foroperating said fans, the blast from said done by means of the wheel 37as has been l fans 1n the vertical cylinders crossing that of the blastfrom the forwardly projecting Having thus described my invention, what icylinders.l
